Hibbard was nothing short of a disaster for the 1994 Mariners. In 15 games, he amassed a 1-5 record with a whopping 6.69 ERA. The 29-year-old also began having chronic shoulder issues that would cause him to miss the final two years of his deal, being capped by reconstructive surgery. The M's invited him to spring training in 1997, but his rebuilt shoulder did not want to cooperate and he announced his retirement on March 10th. He is considered one of the biggest free agent busts in Mariners history.
